Hi all, I've configured lac shaping for upload on my 2811 (ios xxx124-7.bin) as per:
However it's not working. I suspect IOS fault, just wanted to bounce it off someone else.... A "show policy-map session [uid]" gives me no output, eg:
=====================
rt2811_b101#show sss session
Current SSS Information: Total sessions 95
Uniq ID Type State Service Identifier Last Chg
899 PPPoE/PPP connected Forwarded x@x.x.x 11:53:01
rt2811_b101#
rt2811_b101#show policy-map session uid 899
rt2811_b101#
=====================
Relevant components of the router configuration are:
==========================================
!
subscriber profile Profile1
service relay pppoe vpdn group group_1
!
vpdn enable
vpdn source-ip x.x.x.x
!
vpdn-group User2-vpdn-group-domain
request-dialin
protocol l2tp
domain y.y.y.y
initiate-to ip z.z.z.z
source-ip x.x.x.x
local name aName
ip tos max-reliability
!
!arbitrary policing figure for testing purposes...
!

!

!

interface Virtual-Template1
description PPPoE and L2TP
mtu 1492
ip unnumbered FastEthernet0/0.x
ppp authentication chap
ppp chap hostname aName
service-policy input shape-128k
!
==========================================
So, pppoe is WORKING, however upload policing isn't, which means I'm sending excess traffic across the WAN to be discarded at the LNS. Would be much nicer if it could be discarded at the LAC before uploading.
OH, and the Cisco feature navigator says LAC policing was implemented on IOS 12.3 for the Cisco 2811, so I don't think it's platform related....
Any help would be appreciated,
Cheers Muchly, Jerome

Prerequisites for QoS: Classification, Policing, and Marking on LAC
Configure the Routers
You must configure the Client router, the LAC, and the LNS before applying the QoS policy map as described in the "Configuration Examples for QoS: Classification, Policing, and Marking on LAC" section.
Verify the State of the Subscriber Service Switch (SSS) Sessions
You must use the show sss session command to verify that the user sessions are enabled on the LAC.
Configure the Interface
You must configure the virtual-template interface before applying the policy map to the session.

Hello,
in addition to Phillip´s post, you might want to try and apply the service policy in the outbound direction as well.
Also, can you post the full configuration of your router ? Which feature set are you using (IP Base/Advanced etc.) ?
Regards,
GNT

Hi GNT (no name on your profile)... Thanks for the response, appreciated..
Running IOS "c2800nm-spservicesk9-mz.124-7.bin", Software Advisor says it supports LAC policing....
In addition to the configuration originally posted I created the following....
========================
policy-map shape-2048k
description Throttle to 2048K
class class-default
police cir 2048000 bc 600000 be 1200000
conform-action transmit
exceed-action drop
!
!
interface Virtual-Template1
description PPPoE and L2TP
mtu 1492
ip unnumbered FastEthernet0/0.30
ppp authentication chap
ppp chap hostname User2-lac-domain
service-policy input shape-128k
service-policy output shape-2048k
!
========================
That config change unfortunately hasn't made a difference, the "show policy map session uid [uid]" is still not giving me any output.
I'm a little reluctant to post the full configuration, what I put in the original post was all the LAC related stuff. Is there anything in particular you're looking for? I'll post it if you think it's really neccessary....?
Cheers, Jerome

Hi Phillip, thanks for the reply. I've already tried what you've outlined. If you take a look at the information posted about you'll see the SSS sessions and the configured interface. Cheers, Jerome
